Since I have SEEMED to be awol of late... Answered
this is a short SHORT bit of what I've been planning, and doing of late.
The VERY short video shows my young student repeating the "experiment" we've just executed together, but now for the rest of her family.
It is a demonstration that #1: milk has fat/oils in it, and #2 that detergent breaks these up, and #3: that it does so rather rapidly.
By the time I got the camera ready, she'd already poured a little milk into a saucer, and dropped some different colors of food coloring on the surface tension of the milk.
The video only shows the reaction once she drops the detergent onto the coloring (and if you have the volume up, you can hear her little sister in the background go OOOOOO :-) .
My apologies for the very VERY poor quality of the shot, next time I will prepare ahead of time, with my tripod, for any filming I need to do.
